“…MucR represses its own transcription [24] , [39] , [41] . A non-comprehensive list of MucR regulon consists of genes involved in synthesis of various exopolysaccharides ( exo , uxs-uxe-aps ) and c-di-GMP signaling components (GGDEF and EAL containing proteins) [26] , [42] , [43] ; machineries of motility & chemotaxis (VisNR, Rem, Fla, Fli, Mcp and Che) [25] , [27] , [28] , [29] , and conjugation & secretion (Pilus, T4SS, T3SS and T1SS) [27] , [28] ; and various transcriptional regulators and signalling components in general stress response (RpoE2, RpoE5 and CspA) [28] , [44] , [45] , cell cycle (CtrA and SciP) [38] , carbon and nitrogen metabolism (PTS Ntr ), uptake of potassium (Kdp), zinc (Znu), phosphorus (Pho, Pst and Phn), iron (Irr, RirA and Afu), molybdenum (Mod) and sulfur (Ssu) [28] , [29] , [46] . Collectively, the MucR regulon is multifaceted in life cycles of diverse alpha-proteobacteria.…”
